Working Principle and Application

The LL Series Leaf Chain operates based on a simple yet effective mechanism, where force is distributed evenly across the chain, enabling it to handle large loads. This chain is commonly used in lifting equipment and forklift lifting mechanisms, making it a crucial component in many industrial applications.

The manufacturing process of LL series plate chain

The manufacturing process of LL Series leaf chain typically involves several consecutive steps to create the desired link pattern and ensure its structural integrity. Here is a general overview of the manufacturing process:Raw Material Selection: The first step in the manufacturing process is selecting the right raw material for the chain. These materials can include steel, stainless steel or other alloys, depending on the properties required such as strength, corrosion resistance and cost.Cutting and punching: The raw material is then cut and punched to form individual links. This step involves precision cutting and stamping operations using dies and punches to shape the links to the required specifications.Link assembly: The individual links are then assembled into the desired pattern to form the LL series leaf chain. This step may involve welding, riveting, or other joining methods to securely join the links and maintain their structural integrity.Surface Treatment: After assembly, the chain undergoes a surface treatment process to enhance its corrosion resistance, wear resistance and overall durability. This may involve electroplating, painting, chromating, physical vapor deposition (PVD) or heat treatment, depending on the desired surface properties.Quality Control: Finished chains undergo stringent quality control inspections to ensure they meet specified standards and tolerances. This includes defect inspection, dimensional accuracy and testing to ensure it meets the required performance standards.Packaging and Shipping: Finally, the LL Series Leaf Chain is ready for packaging and shipping. It can be individually boxed, palletized, or shrink-wrapped for protection during shipping and storage. Packaging should be designed to prevent damage and ensure safe delivery to the customer.
